  • Patent number: 10458110
    Abstract: A drive-over tile intake guard has a drain tile inlet coupler that rests against the earth surface and does not rise consequentially above the earth. The inlet coupler encompasses and protects the end of a drain tile pipe. A plurality of rods are affixed on a first end to the inlet coupler, and each extend therefrom simultaneously downward into the drain tile and also generally radially toward the center of the tile opening. However, the rods are also each angularly offset from radial to the tile opening center. By angularly offsetting the rods each in the same rotational direction, smaller debris that might block flow through other prior art guards but which will not block the drain tile from functioning will swirl, slip off of the rods and pass into the drain tile, and ultimately be discharged at the outlet end of the drain tile.

The screen also includes a latch mount that connects to the curb inlet and has a latch saddle that receives the latch pin. The screen operates in two modes: (1) a closed mode where the latch pin is disposed of in the latch saddle, inhibiting rotation about the horizontal hinge; and (2) an open mode where the latch pin is dislodged from the latch saddle, permitting rotation about the horizontal hinge and about the vertical hinge.

  • Patent number: 10040217
    Abstract: A masonry tool cleaning and storage device may include one or more bins capable of holding water and adapted to hang from the sides of a conventional wheel barrow. The bins may or may not have lids, which may or may not be attached to the bins. The device may optionally include a combined drying table and water return surface adapted to route water, e.g. dripping from wet tools, back to the water bins. The drying table may include a grated surface that is more or less horizontal while assembled in a working configuration. The grated surface may be above a downwardly sloped surface adapted to return water that has fallen through the grated surface back to the bins. When work is complete, the bins may be emptied of water, cleaned, and used for tool storage.

  • Patent number: 10024043
    Abstract: A pollution trap for storm-water runoff includes a filter-box assembly that provides for top-down maintenance. The filter-box assembly includes at least one filter container, a filter-container support, and a peripheral seal, so the filter container can be lifted from and lowered into the trap from above. The filter container includes sidewalls forming an open bottom and top, a bottom filter support, and a top filter retainer, with the container receiving a stack of intelligently-selected filters supported on the filter support and kept in the container by the top filter retainer. An optional adjustable hold-down assembly holds down the top filter retainer and the underlying filters. The filter-container support holds the filter container up off the trap floor so the storm-water can up-flow through it. And the seal is interposed peripherally between the filter container and the filter-container support so the storm-water cannot flow around the filter container.

  • Patent number: 9963865
    Abstract: A storm water inlet filter system is disclosed which comprises at least two, but preferably three, distinct filter layers. The storm water inlet filter system uses a nested basket structure in which one filter basket fits within another. Preferably a piece of disposable filter media is placed within the internal basket. Polluted water flows first into the inner basket, and onto the disposable filter media. Overflowing water passes into the outermost basket which can remove debris. The storm water inlet filter system can be used with many existing drainage systems, and can be cleaned and the disposable filter media replaced without the use of specialized equipment or training.

  • Patent number: 9869103
    Abstract: A sump drain includes a ring-shaped chamber having an inner sidewall with a diameter of at least about 18 inches and an outer sidewall, and a circular opening between the sidewalls preferably about an inch wide and optionally having a grid cover. Preferably the inner sidewall has a number of ports extending inwardly to radial conduits to a central hub for tying into a pool or spa filtering system, with the central hub operating as a clean out and having a removable cap. Upon installation, plaster substantially fills the space between the chamber and the central hub, such that the sump drain attractively blends in with the pool or spa floor. When installed, the top opening is preferably substantially flush with the pool or spa floor while being safely unblockable. And the sump drain preferably further includes channels both outboard and inboard from the chamber top opening and around the central hub, to help prevent water from passing through the plaster into the shotcrete of the pool or spa.
